Dual Lens Endoscope with Light, Teslong MS450 Automotive Mechanic Borescope

I bought this endoscope to try to find the hole in my HVAC duct which was allowing mice into the vents (not into the actual house, thankfully; they were only inside the ductwork with the vent covers serving as a sort of "jail" which kept the mice sequestered to the ducts). The ductwork is in the crawlspace, but some of the runs are tucked up between the floor joists and hidden by underlayment...meaning I couldn't simply go into the crawlspace to look for holes. That's where this endoscope comes into play. I was able to feed the scope through the vent and down into the ductwork and did manage to find a hole (in addition to a bunch of junk). Since I was feeding it into a fairly large "pipe", it was a bit tricky keeping the scope oriented, as the semi-flexible cable may curve and twist as you feed it in. The more cable you feed in, the harder it is to control. Because of this, I think the 16 ft cable is the longest recommended length...anything longer will be too difficult to control in any space wider than a 2" pipe. I also highly recommend getting the dual lens camera. I found myself switching back and forth between the two cameras a lot. Often, the front camera didn't show much because it was lying directly against the bottom of the duct, but the side camera would show the top or side of the duct. The IPS screen is good quality and a nice size. Resulting video/pictures are good considering the size of the camera. I downloaded the pictures onto my computer and the quality actually looks a bit better on the endoscope screen vs my computer...perhaps because the pics are so much bigger on my computer. I've attached a couple pictures I took with this endoscope, both from inside the ductwork and also through a hole in my floor where a cable line runs (the previous owners of my house were lazy and drilled right through the floor instead of bringing the cable through the wall). This was my first attempt at using the endoscope and I'm sure my pictures will improve as I get better at holding the probe steady. I did find it difficult to figure out if I needed to push or pull to get the camera centered on what I wanted. Perhaps that will also get easier the more I use it. All-in-all, this is a handy little endoscope. In addition to household DIY, I could also see this being useful with car/engine repair. Who hasn't dropped a bolt or nut into a small opening when working on your car or lawnmower? The endoscope comes with a hook and a magnet which would help retrieve said bolt or nut. It also comes with a very nice carrying case.

I do a lot of work on my older house, both as a hobby and to save money. This endoscope has saved me well more money than its cost in the first few months, and severely cut down on the "repairs" from exploratory holes I used to have to put in walls and ceilings. I am not a professional, so I don't use this every day, and I am pretty tech savvy, so the balance of features and usability versus technical knowledge to plug in, charge, and make it work was just right. The endoscope itself feels very solid, the screen is bright and clear, and the camera and light, with the ability to switch from the front to the side camera at the base of the unit (dual camera is great!), giving me good confidence in the longevity. The recording feature has been especially useful, as it captures the video from the camera, but the voice at the base. By narrating what I am doing and seeing on the camera, I can later replay the video either on the unit or at my desktop computer and easily understand what I was seeing. This has also been useful when later showing a contractor what they will expect to see when they tear into the walls! I don't have any real complaints, but I do wish I had bought a shorter probe length. I thought up front that buying a longer one than I needed (I bought a 16ft long probe) would "future proof" my needs. Well, the problem is that in all the uses so far, I haven't used more than the first 4 feet of the probe, and as such the extra 12 feet was curled up, making holding the base unit and the coil of extra probe while trying to manipulate the tip of the probe an exercise in patience and re-doing. That is not a dig on the device, but rather my choice in purchasing. The probe itself is flexible, but holds its shape well. Note that at this price point, the probe is like a microphone stand, you bend it and it stays that shape. It cannot be remotely manipulated once it is inserted into whatever you are looking at. Overall, this was money well spent, with a high quality device, nice case and accessories (mirror and magnet). I highly recommend!

Update again in December 2024: The battery still doesn't hold a lot of charge but has improved since I tried it a month ago. It appeared that after a couple of cycles to using and recharging it, I can use it for longer each time. The video is the latest showing its charging status. The battery aside, this is a great endoscope in terms of the overall build quality, controls, and picture quality. Raised the rating back to 4 stars, with the understanding that some battery degradation is normal after 3 years. Update in 2023: I purchased it in 2021 and used it for a few times on cars and home projects. It worked nicely! However, now in 2023, I wanted to use it again. It was low on battery so I plugged in the USB-C charging cable and it didn't charge at all. I used different chargers/cables with the same result. You can see in the pictures the correct charging port was used and there is no sign it was charging. Couldn't seem to make it work now. I put it in the case and stored it in my toolbox/drawer when not in use. It was never abused. Very disappointed! =========== My original review in 2021 below ============== I've used it for car inspection and checking air ducts in the house. It works great! It comes with storage so you can take pictures and review them on the computer as well. The picture resolution is fine but a higher resolution will help especially when you need to zoom in on certain areas for details. Overall, this is a great tool!

Like a lot of people, I bought one of those $30 endoscopes that require you to use an app on your phone to see the stream. Like a lot of people, I took an hour with it, threw in the towel, and shipped it back. This Teslong endoscope is the real deal. Yes, it's more expensive, but not prohibitively so and for that extra price you get a great picture, lighted dual-cameras (top and side), a sturdy, easy-to-use control unit, and generally good battery life. As soon as we broke it out, we went into the basement to thread it up through the floor to try to identify the source of a leak around the skirt of the tub in our 2nd bathroom. The multi-level light was up to the task of illuminating the darkened cavity and when we needed to sneak up around the side of the tub for a sides shot, the side camera performed well, helping us narrow down exactly where the leak was flowing. The one frustration I have, and it's not unique to this endoscope, is that the flex cable, while strong, still flexes a little too much when you are trying to aim a camera that is several feet away. Our solution was to find a piece of 1/4" PVC pipe that we had laying around, thread the camera up and in, tape the flex cable to the pipe to ensure it was not going to move when we twisted the pipe, and then use the pipe to rotate and aim the camera. This might not work in every situation, but it worked well for us. All in all, the Teslong "feels" like a piece of semi-pro gear, not like a piece of junk like the endoscopes in the $30 range. It's not a pro endoscope, and it lacks some of the resolution and other nice-to-have features of larger, handheld units, but it does the trick for the price. Highly recommended!

Have been using for almost 2 months now and still amazes me with the number of uses. Originally purchased to help run wiring inside walls and within 1st floor ceiling of a 2 story home. For those purposes it works flawlessly - I was able to see top plate penetrations and find my way through a vertical fireblock into a garage area. The depth of field was more than adequate, the light was bright and I could see obstacles clearly. Was also surprised that my stud finder could find the camera wire. For another project, I had to locate a pipe and had no trouble locating to open up the drywall to make a cut. One thing I did find helpful was to place markings every foot of the cord to help me gauge location within the ceiling. I was installing a cold air intake on my truck and dropped a quarter-turn plastic screw into the engine bay where it landed on a skid plate. With the endoscope I was able to quickly locate it and push it onto the garage floor. Overall - a great tool for the money and excellent value - 1080p / great picture and built-in screen is perfect size - love that I can remove the SD card and download to a PC quickly rather than wirelessly or via a phone - dual camera works well and like that can be flipped back and forth without the need for adapters which can fall off - rugged case and easy to use controls - case and accessories are top-notch - have not had a chance to need yet, but waterproofing is a nice to have I previously used another brand/model that required connecting to a phone, which I thought would be better, but did not like the quality, a cumbersome process of saving videos (no removable card) and requiring me to use my phone on ladders, crawl spaces, attics, etc.

I got this because I had ac issues and needed something I could slide it there and look around with. It has a great picture and snaps photos well but the camera is difficult to get in to any position. As a mechanic I have used a lot of different versions of these scopes over many years. This one does work but if your trying to get into difficult areas you may want to find something easier to control. It's great for looking in my ac ducts but trying to look in walls or around an engine bay this can be difficult to use.

Still working today. Great investment.

What do I like about the Teslong MS450? 1) image quality (see photo); 2) side-view camera; 3) easy to use; 4) USB-C charging & computer connection; 5) great tactile feedback on buttons. What don't I like? 1) "switch camera" button location; 2) rigid connection at monitor. Image quality: As shown in the photo, the image from the Teslong MS450 is brighter and clearer, and has a somewhat narrower field of view when compared to the Depstech DS450. Both pictures were taken with natural lighting only - no artificial lighting from the endoscope or other sources. Both pictures were taken at a distance of 3 inches from the ruler in the picture. The field of view of the Teslong is about 70 degrees (this matches their claim), while the Depstech field of view is about 83 degrees. Depth of field on the Teslong (in my testing) is about 1-1/4 inches to 4 inches (also matches their claims). Side-view camera: A side-view camera comes in very handy when you can't approach the subject head on. For my purposes, an example of this would be reading serial numbers on rack-mounted equipment. Sometimes the labels are on the back, very close to a wall, or on the bottom, very close to equipment mounted below. In either case, you may only have 2 inches of clearance - not enough room to bend the end of the scope and point it at the subject. With a side-view camera, you can stick the scope in from the side in a space as small as a single rack unit (1-3/4 inches), and still get a clear image of a serial number or model number, without removing the equipment from the rack. Easy to use: the buttons are intuitively labeled, with the exception of the up/down buttons functioning as digital zoom (up) and 180 degree image rotation (down). My only real complaint about the interface is the location of the "switch camera" button - it's at the base of the scope cable where it connects to the monitor; a button on the monitor itself would make more sense. USB-C: some scopes come with micro USB - an interface that's on its way out. Sure it will still be around for quite a while, but I see no reason to buy a new device that uses a connection that's declining in use. I don't think this has anything to do with USB-C, but the Teslong is automatically "seen" by the computer when connected - allowing you to easily download pictures from the device. Some others (including the Depstech DS450) require you to fiddle with the menus before it's "seen" by the computer - and you have to do this every time you connect. Tactile feedback: the tactile feedback of the buttons is excellent, but I think this is more of a personal preference than an objective thing. Rigid connection: I think this is pretty much consistent across endoscopes in this price range, but the rigidness of the scope makes it difficult to manipulate the position of the scope without also having the monitor move erratically. Expect to use one hand to move the scope, and the other to hold the monitor stationary. If you don't, the monitor may end up on the floor, and I'm not sure how likely it is to survive such a drop, especially if you're on a ladder at the time. More flexibility at the base of the scope would greatly help with this. Overall, I think this is an excellent value, and I would definitely recommend it to anyone looking for an endoscope in this price range.

I bought this camera to check out a clogged grey water drain. The picture is very clear and I was quite impressed with the unit especially for the price. I couldn't end up seeing what the blockage was as the water was very murky, however I was able to see that there were no bends in the pipe so I knew where to dig outside. I also sent it 50' into a drainage big o. I taped it to some fiberglass fish sticks (for running electrical wires) and was able to push it in with no issues.

Good working well

Great quality video and pics can be captured by using this instrument. Very helpful in automobile field

Bought this to inspected my well. Worked perfect, the light is bright and screen is clear. Highly recommend

Bought this for a specific task but can’t count the times I’ve used it!😌☺️😎
